With wordpress MU setups, you need to manually set up the blog id
( well, at least I have so far )... here's some extracts from one of my
site configs:

map $http_host $blogid {
	default	0;
	example.com.au 2;
	example.com.tw	3;
}

location ~ ^/files/(.*)$ {

try_files /wp-content/blogs.dir/$blogid/$uri /wp-includes/ms-files.php?file=$1 ;
	}

and

location ^~ /blogs.dir {
	internal;
        alias /www/example.com/public_html/wp-content/blogs.dir ;
	expires max;
}

If that still doesn't work, can you check that you've got everything
connected correctly by delivering a quick <?php phpinfo(); ?> file to
your browser?

There are example configs on the net - wordpress offers one for certain,
and googling for wordpress, mu and nginx deliver a plethora of howtos.
Why not begin with one of them and try to understand it, rather than
fighting to reinvent the wheel?
